I have never hated any position in baseball more than I loved playing.
If you think you can approach your coach and ask if guys will have a shot to earn other spots you can do that. The fact that you have had conflicts with this coach before means he may very well have you pegged as an attitude case. It doesnt even really matter if it is true or not. If that is his perception it will be up to you to prove him wrong.
At this point I would advise you to work very hard this offseason, dont miss sessions for conditioning, work harder than everyone else, do what the coach asks, be respectful and if asked to play first during practice or drills do with as much energy, skill and hustle you can. Showing you care and you want playing time will get you your best shot at time. Arguing, complaining, displaying attitude will do nothing but show you the bench.
